. adjustable mechanism by means of which either left hand or right handcoils can be formed.

The more detailed objects of this invention will be apparent from thefollowing description of several embodiments thereof when taken inconnection with the attached drawings.

'I'his invention resides substantially in the combination, construction,arrangement and relative locations of parts as will be.decribed indetail below.

In the accompanying drawings,

In the manufacture of wire, as for example copper wire, man1 usersthereof require that the wire be put up in the form of open coils ratherthan wound on spools or reels. Furthermore, in adapting these coils tocertain uses the users frequently require that the wire be ,formed intoleft vhand coils as distinguished from the .more usual requirement thatthey be formed into right hand coils. The coiling machines as commonlyemployed for forming right hand coils are not adapted, at least notwithout considerable change,

sult thatseparate machines have been considered preferable for theforming of the two kinds of coils. This, of course, requires extensiveand 'undesirable duplication of machines in order to equip a factory forthe production of both types o! coil.

In accordance with this invention there is provided in a single machinemechanism which may be easily adjusted so that the same machine may beemployed to form either left hand wound or right hand wound coils.The'manner in which' this is accomplished will be quickly understoodfrom the following description in det-ail of two 'embodiments of theinvention.

Referring` first to the structure illustrated in Figures 1 to 6inclusive there is illustrated at I the last capstan wheel shown mountedon a power driven shaft 2. The wire W passes from the next to the lastdrawing die in the wire drawing machine to and once or more times aroundthe capstan wheel I, which being power driven by mechanism not shown,acts to draw the wire from the next to the last drawing die. The wire Wpasses from the capstan wheel I to and through a. passage or spacebetween a pair of idler guide wheels 3 which are freely and rotat` ablymountedon a bracket 4 mounted on the end wall of the casing I. 'I'hewire engages one or the other of these idler wheels I, depending uponwhether a right hand or left hand coil is being formed, as will bereferred to again.

The end wall of the casing has an opening and the region of the openingis preferably reinforced as indicated at B in Figure l, to form a baseupon which the adjustable holder for the ilnal drawing die is mounted.Resting against 'this base is a wedge-shaped block 1 which is attachedto the base by means of a. pair of locking bolts i which lie in theradially aligned slots/in the block. Attached to the outer face of theblock i is aplate 8 which is attached thereto/by means of bolts 8' 1which pass through elongated slots in the plate to the formation of lefthand coils, with the re- 8. As is clear from Fgure 5, by means of thisconstruction the pla 8 may be adjusted verti- 4cally within limits abovethe face of the block 1. 'I'he plate I, as is clearly shown in Figures 4and 6, is provided with a passage aligned with the passage in thehousing 5 and the block 1, which is spherical in form to provide a seatfor the die block holder I0 which is complementarily shaped so. as torest in this seat. The holder I0 is attached to the plate 8 by fourscrews I2 and cooperating washers Il, so that it may be ley/ed to theplate 8 with its longitudinal axis a any desired angle with respect tothe plane of the plate 8. This holder I0 in actual use is only subjectedto slight angular adjustments in order to properly align the die I3which is mounted and locked therein by means of a tubular lockingbushing I4. The die I3, of course, has a passage through it inaccordance with usual practice, of a diameter such that when the wine isforcibly drawn therethrough it will be drawn out into a wire of nnergauge, which, of course, will be the final wire size. v

The wire W then passes to the coiler block which is power driven andprovided with mechanism for causing it to rotate either in the righthand direction or the left hand direction, that is clockwise orcounterclockwise. as viewed in plane (Figure. 2). The coiler blockconsists of a truncated conical tubular element. Il which is providedwith an internal re-entrant hub I! by means of which it is locked on apower driven shaft I1. Bolted to the lower end of the tubular element Iiis a skirt I8 having a conical mainbody. The coiler block, comprisingthe members I5 and Il as herein disclosed. isshown inthe formcommonlyused in this art. The flanged terminal end of the skirt Il is inclinedat a slight angleradially, as clearly shown in Figures 1 and 3, and thewire is delivered to the coiler block where this flange portion joinswith the main body portion. Thus', in accordance with the usual practiceeach succeeding coil is delivered into the resulting fillet of annularform, and pushes the preceding coil upwardly, the block being slightlytapered, as shown, so that its upward movement loosens the succeedingcoils as they are formed and travel upwardly.

The shaft is journaled in bearings I9 mounted in a suitably shapedsupporting member 25'. The lower end of shaft I1 is provided with abevel gear 2l which meshes with a pair of companion bevel gears 2| and22. The gears 2| andv22 are freely rotatable in the bearings 23 and onthe shaft 28 which passes through them and is journaled at one end, asshown, in the bearing 2S. Splined on the shaft 28 in the space betweenthe gears 2| and 22 is a' clutch sleeve 25 provided with clutch teeth onits endsv to cooperate with similar clutching teeth on the adjacentfaces of these gears, as clearly shown in Figure 3. Pins on the ends ofthe-arms of yoke 2i engage in an annular groove on the surface of theclutch sleeve 2l. The yoke is mounted through which the driving powerfor the coiler is provided.

In the operation of this machine, assuming that shafts 2 and 28 arerotating, the wire-passes from the capstan 8|, which pulls it from thepreceding die to and through the final die I3 and around the coilerblock which is revolving. Assuming that lever 3| has been turned toproper position, clutch sleeve 25 will connect the correspo ding one ofthe pair of gears 2| and 22 to the shaft 28, with the result that theblockV will revlvelthrough power applied by the gear 20. Assuming that aright hand coil is being formed, as indicated in Figure 2, the coilerblock 75 will be revolving in a clockwise direction and the wire afterleaving the capstan wheel I will engage the uppermost (Figure 2) of thetwo idler wheels 3 so that it can be deected to the upper side of thecoiler block (Figure 2). If it is desired to prepare a left hand woundcoil, the operator removes screws 9 so that the wedge-shaped block 1 maybe reversed from the position shown in full lines in Figure 4 to thedotted line position shown in the same figure. It is attached in thisposition and plate l is attached thereto by means of the screws 8. Bythe proper adjustments of the blockl 1 and plate 8, because of rtheslotted passages for the corresponding locking screws, the die may beproperly aligned. In adjusting the apparatus for the formation of eithertype of coil the die blck holder I9 can have its longitudinal axisproperly aligned with the path of travel of the wire by loosening andagain tightening the screws I2. yBy reversing the wedgeshaped block 1the parts will be aligned so that the wire W nowengages the lower idlerwheel 2 (Figure 2), so as to be delivered to the opposite side of thecoiler block. Lever 3| is repositioned so that the clutch sleeve 25 nowengages the other of the gears 2| and 22, with the result that thecoiler block is caused to revolve in the opposite direction. Thus bythose few simple adjustments the machine can be quickly adapted for thefor-- mation of either right hand or left hand coils.

For the operation of the machine'at different speeds the change gears,including the gear 2l, can be properly selected and when coils ofdifferent sizes are made coiler blocks of proper diameter can be mountedon the shaft |1. Thus the machine is universal in its application to theformation not only of coils of 'different wind, but of different sizes.

In Figures '7 and 8 is shown a modified ar- 'rangement for effectingsimilar changes by mechanism which makes these changes simpler. In thisarrangement the guide wheels 3 are rotatably mounted at one end of asegment shaped plate 4I which is pivotally mounted at 45 on the end wallof the wire drawing machine. The plate 49 is provided with teeth 4| onits segmental edge, which mesh with a worm wheel 42 supported forrotation by means of a hand wheel 43. The

M'opening in the end wall in which,the plate 4B is 'mounted isprovidedlwith a curved cover plate 4l having `an, opening'inwhich theparts may move.

- Mounted on the plate 40zis a bracket 46 .to which the die blockholdery plate 41 is attached. This plate corresponds to the plate 8 ofthe previous 'I construction and provides a socket for the holder 48 forthe die block, which may be constructed as before. The coiler block andthe drive mechanism is similar to that previously described but in theform shown the yoke 2B is directly provided with an extending arm 5|!pivotallymounted on the` housing so that the yoke can be moved to shiftthe clutch sleeve 25 directly in a manner similar to that previouslydescribed.

As will be apparent from the drawings in view of the previousdescription, the die block holder ciples of this invention may bemodified in other physical forms, and I do not, therefore, desire to bestrictly limited to the disclosure which has been presented in anillustrative sense, but rather to the scope of the claims granted me. Inthis connection it is pointed out that the principles of this inventionneed not necessarily be applied for use with a wire drawing machinesince the apparatus is capable of use with any other machine from whichstrands are delivered. Likewise, the coiling mechanism may be used alonefor ceiling purposes, as for example in forming coils from wire mountedon reels or spools..

The principles of this invention are not limited to a structure in whichthe coiler block is supported from below so as to stand erect, but itmay be equally well applied to a machine in which the drive is above sothat the coiler block hangs downwardly. Likewise, when desired, the axisof rotation of the coiler block may be arranged horizontally.

In a machine of the type described the combination including a powerdriven coiler block, means for causing rotation of the coiler block ineither of two directions, a die holder, and means for selectivelypositioning the die holder for supplying a strand to the coiler blockalong either of two paths tangential to the coiler block at oppositesides thereofd v 2.
